<p>An information disclosure vulnerability exists in Microsoft .NET Framework that could allow an attacker to access information in multi-tenant environments. The vulnerability is caused when .NET Framework is used in high-load/high-density network connections where content from one stream can blend into another stream.</p> <p>To exploit the vulnerability, an attacker who can access one tenant in a high-load/high-density environment could potentially trigger multi-tenanted data exposure from one customer to another.</p> <p>The security update addresses the vulnerability by correcting the way .NET Framework handles high-load/high-density network connections.</p>
